lets say fx you play 3 hours on EU1, not counting downtime with mapchange etc. that will give you 180 ticks, you need 48 ticks to cover 24hours of crafting in strategus,
that gives you 80 hours of crafting build up, which will decrease each hour, and ofcourse gain more when you get more ticks. so basically, 3 hours of EU1 per 3,75 days, that doesnt sound to hardcore to me, play 6 hours a week for a full week of crafting...
